Abstract :
The authors describe a synchronization method for short length words that uses message dependent synchronization digits. To each message to be transmitted, redundant digits at the encoder side are assigned. The redundant digits depend on two neighbor messages and are chosen so that at the decoder side maximum separation can be detected between the synchronized and unsynchronized modes. They analyze the decoding performance for transmission over an AWGN (additive white Gaussian noise) channel with synchronization transition errors. If the length of the messages is taken as equal to 8, then the method can be used to achieve symbol synchronization for length-255 Reed-Solomon codes. Simulation results are given for hard as well as soft decision decoding
